This model is discontinued
AirTAC has phased out the SU series. You can still order this code here: we ship the direct replacement SAUJ50X110-30S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAU replacement uses the same profile body, bore, stroke, force and SC-series mounting. It moves to the current CMSG / DMSG / EMSG sensor switches (the SU used CS1-B / DS1-B) and adds the SAUF valve-integrated option.
Airtac SUJ Adjustable Cylinder SUJ50X110-30S
The AirTAC SUJ Adjustable Cylinder SUJ50X110-30S is a double-acting profile-type standard cylinder with a Ø50mm bore and 110mm stroke, 1/4" air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAUJ50X110-30S, which matches its bore, stroke, force and mounting.

About the Airtac SUJ Adjustable Cylinder SUJ50X110-30S
The AirTAC SUJ50X110-30S is a double-acting double-rod profile cylinder with an external stop screw that lets you trim the extend stroke by up to 30 mm on-site, yielding a usable 80-110 mm stroke from the 110 mm nominal maximum. It features a 1/4" port, an M16x1.5 rod thread, and 21 mm adjustable air cushions at each end. This discontinued unit carries a built-in piston magnet for legacy CS1-B/DS1-B switches.
This SUJ50X110-30S is discontinued; the direct replacement is the SAUJ50X110-30S, which retains the bore, stroke, force, port, and SC-series FA/LB mounting. The SAUJ upgrades sensing to current CMSG/DMSG/EMSG switches and offers the SAUF built-in-valve variant. The stop screw sets the end position but is not a load lock; use an external rod lock for held loads.

Specifications follow the official AirTAC SU datasheet (now discontinued). The SAUJ50X110-30S carries the same ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
Theoretical Output Force (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 kgf | |
The SAUJ50X110-30S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

| SU | Profile-type standard cylinder (discontinued). |
|---|---|
| 50 | Bore size in mm. |
| ×110 | Stroke length in mm. |
| -S | Optional built-in magnet for sensor position sensing. |
Legacy SU-family variants: SUD (double rod), SUJ (adjustable stroke) — each maps to its SAU equivalent (SUD→SAUD, SUJ→SAUJ). The current SAU line adds the SAUF valve-integrated option.
Where the Airtac SUJ Adjustable Cylinder SUJ50X110-30S Is Used
Variable-Length Ejector
Tuning the extend stroke by up to 30 mm on-site lets an ejection pin hit varying material widths without re-mounting the cylinder.
Adjustable Transfer Stop
A 50 mm bore transfer stopper uses the external screw to set precise 80-110 mm protrusion heights for mixed product sizes on the line.
Replacing the Airtac SUJ Adjustable Cylinder SUJ50X110-30S with the SAUJ50X110-30S
To replace the discontinued SUJ50X110-30S, specify the SAUJ50X110-30S direct, matching the 50 mm bore, 110 mm stroke, 1/4" port, and FA/LB mounting. The -30 mm adjust window lets you tune the extend end position on-site (80-110 mm usable); if you need less fine-tuning, a -20 mm window works, or step up to a 63 mm bore for more force. Because this unit has -S, swap the legacy CS1-B/DS1-B sensors for CMSG/DMSG/EMSG switches. For strokes of 300 mm or longer, verify side-load limits to prevent rod binding.
Replacement checklist
- ✓ Same bore / stroke → SAUJ50X110-30S
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S): sensor family CS1-B → CMSG
- ✓ Mounting reused (FA/FB/CA/CB/LB)
- ✓ Need a built-in valve? → SAUF
Airtac SUJ Adjustable Cylinder SUJ50X110-30S FAQ
Yes, the SUJ50X110-30S is discontinued. The direct replacement is the SAUJ50X110-30S, which matches the 50 mm bore, 110 mm stroke, 1/4" port, and FA/LB mounting. You must upgrade the legacy CS1-B/DS1-B sensors to current CMSG/DMSG/EMSG switches.
The external stop screw trims the extend stroke by up to 30 mm on-site, giving an 80-110 mm usable range. The stop sets end position and is not a load lock.
